Ethereum’s Glamsterdam upgrade enters final development stage with closed devnet testing

Ethereum developers have entered the final stretch of work on Glamsterdam, the network’s next major upgrade, as teams begin testing a version of the fork in closed developer networks. According to CoinDesk, the devnets include the full suite of Ethereum Improvement Proposals slated for the upgrade, ahead of hardening the codebase and deploying to public testnets; no activation date is set, though it is expected to go live during the second half of the year. Headline changes include enshrined Proposer-Builder Separation (EIP-7732), Block-level Access Lists (EIP-7928), and gas repricings that could alter Ethereum’s fee economics.
